And Patrick Dempsey rides with THR to celebrate Bike to Work Day.

Can't keep up with what's been going on in the social media world? Fret not. Here, a gathering of what the stars have been up to this week on social media.

Leonardo DiCaprio's Chanel Purchase
Leo dropped $18,100 on a Chanel bag — but relax, boo-boo, it's for his mom. For the second year in a row, the Oscar winner purchased a Chanel bag at The Heart Fund’s Generous People Dinner Gala in Cannes and reportedly gifted it to his mama instead of one of his model girlfriends. The heartthrob reportedly purchased silk scarves, too.

Hermes Guy in Cannes
The Hermes store in Cannes is popping with well-to-do clients trying their best to purchase the Kelly bag off the shelf. And the man to mingle with is Michael Coste, head of external relations at The Hermes Group. Coste shared an Instagram shot of himself having dinner with Kris Jenner at the Cannes Hotel Martinez in the kitchen of two-time-Michelin-starred chef Christian Sinicropi. A guy who can get you on Hermes’ infamous years-long waiting list and take you to a fancy dinner? What a keeper.

Kirsten Dunst's Cannes Style
If you need something new in your feed, check out Dunst’s style gurus, Nina and Clare. The pair shoot candids of Dunst, with images cropped and filtered to perfection. Plus, you get incredible behind-the-scenes scoop on the actress' looks. Post to look for: Dunst’s Cannes jury wardrobe. The stylists sewed a Chopard necklace into a gown and dressed Dunst in a straight-off-the-Havana-runway Chanel dress. Baller.

Unconsciously Dressing
Chris Martin and Gwyneth Paltrow were trending online for most of the week over a photo from Paltrow’s Instagram feed. The amicable pair took daughter Apple to Disneyland for her 12th birthday. But fans weren’t so nice. They wanted to know why Martin was completely bundled up. "Wearing a puffy coat at Disneyland... This is why I have trust issues," wrote one user. Anaheim, Calif. averaged around 70 degrees this week — hardly calling for a puffer jacket, sweater and wool cap. A Goop post on "What to Wear to Disneyland" would have come in handy.

Braids for Days
We totally paused over Mad Men sweetheart Kiernan Shipka's new do this week. The teen rocked double French braids (as seen on the Kardashians and co.) with extensions. After a day, Shipka unbraided her mane and headed to Monaco to celebrate joining The Net Set’s Style Council.

Billionaire David Geffen's Leo DiCaprio Shot
DreamWorks founder, producer and philanthropist Geffen posted a photo of pal Leonardo DiCaprio on his yacht in Cannes this week. The bearded actor, who doesn't look too far off from his character in The Revenant with his facial hair, donned a clean white tee, Persol shades and slicked-back hair. And in case you're still wondering who Geffen is, follow the instructions in his Instagram bio: "Google me."

Happy Bike to Work Day!
Patrick Dempsey, aka McDreamy, rode with THR staffers from Santa Monica to The Hollywood Reporter’s Wilshire office to celebrate Bike to Work Day, organized by THR features editor Peter Flax. Emmy-nominated writer and producer Tom Smuts (Mad Men) joined the #RideOnHollywood fun. Smuts is no stranger to long rides — the producer led a 15-person bike ride to the 2015 Emmys.
